A component called a reflectron, which directs the incoming ions at the ion detector, is often incorporated into the mass spectrometer. When the ions strike the detector, it records the event as well as the charge of the ion and the elapsed time in flight between the ion generator and the...
How a Mass Spectrometer Works The three main parts of a mass spectrometer are theionsource, the mass analyzer, and the detector. Step 1: Ionization The initial sample may be a solid, liquid, or gas. The sample is vaporized into agasand then ionized by the ion source, usually by losing ...
A mass spectrometer is an instrument which ionizes a sample, separates the ions depending on their mass-to-charge ratio, and measures the intensity of the ions present at different mass-to-charge ratios. This can be used to determine the elements or isotopes present in the sample. ...
I What is the function of the magnetic field in a mass spectrometer? B A. It detects the mass of the particles. B. It deflects the stream of charged particles. C. It excites electrons to higher energy levels. D. It produces a stream of electrons that bombards the sample. 相关知识点...
In the broadest sense a spectrometer is any instrument that is used to measure the variation of a physical characteristic over a given range; i.e. a spectrum. This could be a mass-to-charge ratio spectrum in the case of a mass spectrometer, the variation of nuclear resonant frequencies in...
How does an optical spectrometer work? The Spectroscopy Process A transmission optical spectrometer is used to measure the absorption (or reflectance/transmission/emission) of a sample in the near UV throughout the visible region of the spectrum. The spectrometer consists of a light source, a dispe...
